linsmith: Smith Charting program

linSmith is a Smith Charting program, mainly designed for educational use.
As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation.

It's main features are:

-Definition of multiple load impedances (at different frequencies)
-Addition of discrete (L, C and transformer) and line components (open and closed stubs)
-Connection in series and parallel
-A 'virtual' component switches from impedance to admittance to help explaining (or understanding) parallel components
-The chart works in real impedances (not normalized ones)
-Direct view of the result on the screen
-Ability to generate publication quality Postscript output
-A 'log' file with textual results at each intermediate step
-Load and circuit configuration is stored separately, permitting several solutions without re-defining the other (this may actually change to single files - I'm not quite convinced here)
